dear sir/madam
The multilying the denominators of two fractions is a simple logic
instead of taking l.c.m of the denominators and then adding with
the base of l.c.m.it i the logic of intermitent fractional
addittion and would out with very extreme cases.but it involves
a lot of calculations for bigger fractions
